Bread
Overview
Bread is a food made by mixing grain flour (mostly wheat flour) with water, salt, and a leavening agent, kneading the dough, and baking it with heat. It is one of the oldest processed foods in existence, dating back to the Neolithic Age when humanity began agriculture, and today it is also a cultural symbol whose forms and meanings have become extremely diverse according to region, religion, and social class. For a large share of the world's population, bread is not merely a side dish but the staple that forms the basic framework of three meals a day.

Etymology and Definition
The Korean word "빵" (ppang) is known to derive from the Portuguese word "pão." A term that originally referred to Western-style leavened bread introduced through Portuguese merchants and missionaries after the 16th century gradually expanded to cover all baked grain-dough products. It was also during this period that the word became established in Korean as a concept distinct from tteok (rice cakes) made from rice.
History
The oldest traces of bread are the flat, unleavened breads found at Natufian culture sites in northeastern Jordan, dating back about 14,000 years. In ancient Egypt, around 3000 BCE, the method of leavening by accidentally exposed yeast was established, and this spread to Greece and Rome. By the Roman era, a guild of professional bakers (collegium pistorum) already existed, and in the 19th century, with the development of the Vienna method and the steam oven in Austria and France, today's system of baking techniques was completed.
Classification and Types
Bread is broadly divided according to leavening method and ingredients.
- Unleavened bread: The flatbread family, including tortilla, naan, pita, and Indian chapati.
- Yeast-leavened bread: Baguette, ciabatta, sandwich bread, rye bread, and most other mainstream Western breads.
- Soda bread: An Irish bread that uses baking soda as the leavening agent.
- Pastry: Croissants, Danish pastries, and others made by folding butter into the dough to create layers.
- Sweet breads and cakes: Dessert-type breads with a high proportion of sugar and butterfat.
Manufacturing Process
The basic process consists of the following order: weighing → kneading → first fermentation → punching down → dividing and rounding → intermediate proofing → shaping → second fermentation (bench time) → baking → cooling. During fermentation, yeast breaks down sugars to produce carbon dioxide and ethanol, and this gas is trapped in the gluten network, causing the dough to expand. Inside the oven, starch gelatinizes at around 60°C, and above 150°C the Maillard reaction and caramelization occur, forming a brown crust and flavor.
Nutrition and Health
Bread is a major source of carbohydrates, and whole wheat bread is rich in dietary fiber, B vitamins, iron, and zinc. On the other hand, white bread made from refined wheat flour has a high glycemic index (GI), so excessive consumption carries the risk of blood sugar spikes and obesity. In recent years, as awareness of gluten sensitivity and celiac disease has grown, the gluten-free bread market has expanded rapidly. Sourdough, which uses a long fermentation time, is reported to break down phytic acid and thereby improve mineral absorption.
Bread Culture Around the World
Germany has registered more than 300 kinds of bread, the most in the world, and France legislated its production methods in 1993 through the "Traditional Baguette Law." In the Middle East and Central Asia, naan and lavash are at the center of the table, while Mexico's tortilla, India's naan and roti, and Ethiopia's injera reflect the staple grains of each region. In East Asia, a rice-centered food culture was traditionally maintained, but after modernization, a Korean bread culture took shape by way of Japanese-style Western confectionery such as sandwich bread, red bean bread (danpatppang), and castella.
Recent Trends
The key words for the baking market in 2024–2025 are "premiumization," "health," and "sustainability." First, artisan bakeries using sourdough and natural starters are spreading mainly in large cities, and bread is being redefined from a simple staple into an experiential consumer good. Second, functional breads marketed as low-sugar, high-protein, and high-fiber, along with the use of alternative grains such as oats, rye, and buckwheat, are increasing. Third, as unstable wheat harvests caused by abnormal climate and fluctuations in international grain prices directly affect baking costs, the use of domestically grown wheat and upcycling (making use of "ugly" bread) have emerged as industrial topics. In addition, frozen dough technology and AI-based fermentation and baking automation are being introduced at large franchise bakeries, making the trend toward pursuing both quality uniformity and labor cost reduction clear. Meanwhile, as K-bakery items (salt bread, croffle, dujjonku [Dubai chewy cookie], etc.) draw attention in overseas markets, cases of Korean-style bread being exported as a form of cultural content are also increasing.
